Arrhenius Acid Definition: Hydronium breaks up to yield an H+ in solution. Arrhenius Base Definition: Hydroxide is an OH-dissolved in water. Bronsted-Lowry Acid Definition: Hydronium is an H+ donor regardless of solution. Bronsted-Lowry Base Definition: Hydroxide attacks and accepts the H+ from hydronium.Lewis Acid Definition: The H+ on Hydronium accepts the attacking electron pair to form a bond.ronsted-Lowry Acid Definition: Hydronium is an H+ donor regardless of solution.

It is believed that the first Ancient Chinese fire works were made in Han Dynasty (206 BC-220 AD). Fireworks in Ancient China were originally used for shows, christenings and special funeral ceremonies.
But where and when did fireworks originate? Fireworks are a Chinese invention and the first âfirecrackersâ date back all the way to the time of the Han Dynasty, around 200 B.C. While these âfirecrackersâ were simply dried bamboo chunks thrown into the fire to sizzle and eventually explode.
